West Ham beat Tottenham Hotspur 2-1 on Sunday to move into fourth place in the Premier League, with Chelsea dropping into fifth place.
West Ham are now 2 points ahead of Chelsea with 13 Premier League games left to play.
After West Ham moved into fourth above Chelsea, West Ham boss David Moyes told Sky Sports: “I’ve told them that they’ve only done half the job. I think if we continue this way then we’ll be close.
“I don’t want to be negative in any way, it’s a great result for us to beat Spurs with the ambitions they’ve got at their disposal.
“So we are enjoying it, but also we’re not going to go daft. We’d be stupid to say anything and we’re going to keep calm about it.
“But hopefully we keep pushing pressurising the teams near the top of the table.”
West Ham have taken six wins out of nine in the league since the turn of the year, with their only defeat being a 3-1 loss to champions Liverpool.
